PIPE-CAP.

Specification of Letters Patent.

Patented Nov. 19, 1907.

Application filed March 22. 1907. Serial No. 363,829-

To all whom it may concern. I

Be it known that VVILLIAM H. BLOOD, Jr., residing at \Vellesley, in the county of Norfolk and State of Massachusetts, has invented certain new and usel'ul Improvements in Pipe-Caps, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates broadly to improvements in appliances adapted to be affixed to the ends of a cable conduit to secure the latter to an adjacent support, such as a wall or the like, and at the same time shield the open end of the conduit against the admission of water without interfering with the egress of the electrical conductors contained within said conduit.

More particularly, however, this invention deals with certain improvements in my earlier form of pipe cap, which I have dis closed and broadly claimed in my co-pending application No. 353,012, filed January 19, 1907, whereby the same is simplified in construction and is better adapted for practical use under certain conditions.

Inasmuch as certain of the particular advantages characteristic of this invention prominently appear in the herein illustrated specific application thereof, it will be conducive to clearness to disclose it through such embodiment.

This invention has for its object to provide a device of the foregoing nature commonly known in the art as a pipe cap which, in general, may be said to comprise an annular collar, capable of being initially secured to both the end of the conduit and to the adjacent support, and also an overlying hood which in turn is adapted, for being subsequently secured with great facility to the collar.

Another object of the invention is to so devise the various parts comprising the pipe cap that they may be very easily assembled and secured, not only together but to both the conduit and the supporting wall or pole, as the case may be, by means of a single bolt and without involving the difiieult manipulation of small screws and the like.

Still another object is to obtain a pipe cap comprising a collar having a vertically extending rear ear which is suitably apertured for the reception of a bolt whereby it may be secured to the adjacent support, and which collar is so designed as to be capable of being readily fitted over or otherwise socured to the conduit.

The invention also proposes a hood, adapted to be used in conjunction with the aforesaid collar, having a vertically extending rear lug which is com i lemcntary to the aforesaid ear, and is also adapted to be engaged and fixed in place by the retaining bolt.

Other objects and advantages will be in part obvious from the annexed drawings, and in part pointed out in the following description.

In general, this invention seeks to provide a means of the class described. which from an electrical standpoint will in practical usage possess a high degree of effectiveness, and which structurally considered, will be of the greatest possible simplicity and be composed of but few parts each capable oi being manufactured at a minimum of cost and so correlated as to be capable of being very readily assembled by the ordinary worker in the art to accomplish the purposes intended.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the following claims.

In order that this invention may be more fully understood, and made comprehensible to others skilled in its relating arts, drawings illustrating one of the various applications of the same are appended as a part of this specification, and while the controlling principles of the invention may be otherwise applied by modifications falling within the scope of the claims, the herein disclosed embodiment is that which will ordinarily be resorted to in practice, and is regarded as representing substantial improvements over many of the obvious and implied variations of the same.

In the appended drawings, corresponding parts are similarly referred to by like characters of reference throughout the figures, of which Figure 1 is a side sectional elevationshowing the parts assembled, and showing the general relationship therebetween; Fig 2- is tioned by means of the single bolt 6.

a front sectional elevation, or in other words, a vertical medial section taken transversely through Fig. 1, showing the arrangement of certain parts not clearly apparent from said figure; Fig. 3 is a top plan view of the device showing the parts assembled; Fig. 4 is a side sectional elevation of the hood, disassociated from the webless collar. Fig. 5 is a front sectional elevation of the disassociated hood;

Fig. 6 is a top plan view of said. hood; Fig. 7

is a side sectional elevation of the webless collar alone; Fig. 8 is a front sectional elevation of the same; while Fig. 9 is a top plan view thereof.

Referring now to the aforesaid figures, B represents the collar which is preferably webless as shown, and is adapted for being mounted on the extreme end of the conduit. To this end the collar may comprise an annular portion 1, which may be of some little length and may have its interior surfaces smoothand of suflicient diameter to be readily slipped over the end of the conduit. Since the latter will ordinarily be secured to the retaining wall along intermediate or other portions and be thereby prevented from undergoing a downward longitudinal displacement, it will usually suffice for the collar to prevent transverse and upward movement of the conduit, and I accordingly propose to eliminate where possible the customary threaded connection between the collar and the conduit, as the threading and fitting together of these parts involves a considerable expense and inconvenience. It will be understood, however, that such threads may be provided if so desired, as shown by Fig. 2. The upper rim 2 of the collar is preferably rounded and also shouldered at 3, so as to provide a bore which will be substantially flush with the inner surface of the conduit in order that the cable may pass therethrough without any liability of abrasion, and also in order that the relations between the collar and the conduit may be more definitely and easily predetermined. Here it may be noted that this invention also proposes a set screw 14, which may in certain cases be employed to establish a fixed relation between the conduit and collar when the screw threads have been dispensed with. At its rear such collar is provided with a vertically extending ear 4, which is orificed at 5 for the passage of a retaining bolt 6 so that it may be secured to the support. That is to say, the ear extends upwardly in the same direction as the conduit so that it may be said to lie in the vertical plane defined by the axis of said conduit so as to bring its orifice for the bolt directly over the end of said conduit. It will at once be perceived that this very sim ple and easily made collar can be quickly slipped over the end of the conduit and posi- Because of the peculiar arrangement of the parts, the bolt will be positioned directly over the end of the conduit so as to lie in the plane passing of said conduit, as a result of which, any strains which normally tend to cause a separation of the pipe cap pass directly against the end of the conduit and do not tend to cause the pipe cap to swing to one side. When setting up the device, however, this bolt will not in the first instance be driven or screwed entirely home until the hood A has been put in place when, because of the peculiar corelationship between the interfitting parts, by completely driving or screwing home the retaining bolt the hood and the webless collar will simultaneously be bound together.

The hood A merely consists of a dome 7 of suitable contour which is preferably somewhat elongated and spread so as to entirely clear the collar at the sides and front, as shown by the drawings. able advantage resides in this arrangement inasmuch as a free space 8 of considerable size is provided for the egress of the cables, and. at the same time by having the hood appreciably distanced from the collar at the sides, as shown at 9, the flow of water from the hood to the collar along an intervening web or body portion (which the shown specific embodiment of this invention does not have) is entirely prevented, and the water will drip from the lower edges of the hood. Such edges may be provided with a plurality of small teats 10, shown in Figs. 1 and 4, which will drain all the moisture from the inner and outer surfaces of the hood and keep the latter dry, and which will also enable the water to drop more freely from the hood and prevent the formation of icicles in cold weather. At the rear, the hood is provided with a vertically extending lug 11, which is complementary to the ear 4 of the collar, and whlch preferably, as shown, is bifurcated or apertured at its upper end and thereby adapted for being conveniently slipped over the shank of the retaining bolt 6, so that upon tightening the latter all the parts may be simultaneously secured together. The slot in the lug may of course 0 en from the sides. To promote the interfitting of the hood and collar, the latter may be provided'with a recess 13 into which is seated a complementary part of the hood, which part may form the bottom of an analogous recess 12 in the hood, and in this manner the hood and collar maybe locked against relative movement in a horizontal plane. It will thus be readily appreciated that the assembling of the several parts may be very easily done without the assistance of special tools or appliances and without involving the use of small screws or other attaching means, which are so likely to become loose during the mounting of the parts.

As many changes could be made in the above construction, and many apparently A very considerwidely di'll'erent embodiments of this invention could. be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative, and not in a limiting sense. It is also to be understood that the language used in the following claims is intended to cover all the generic and specific features of novelty of the invention herein described and all statements of scope thereof which as a matter of language might be said to fall therebetween.
